IAS 02

Intelligent Axis System, 2 axis

IAS 02 is a powerful CPU module for axis control or management, it features the standard Eurocard format size 100x160 mm. It relies on the powerful 16 bit Abaco® Industrial BUS and exploits the numerous intelligent and non intelligent peripherals available on this BUS.

The board is based on the family 51 Intel CPU in its several versions with or without internal ROM/EPROM, including the masked model with BASIC, and has installed a complete set of peripheral circuits. Should the User need to improve the number of operations per second it is possible both to increment the clock frequence and to install, as CPU, the very fast models 80C320 manufactured by DALLAS. Under the same clock, using this CPU allows to have an average increment for the throughput of threehundred percent.

CPU IAS 02 is the ideal Low-Cost component for all the applications that need to control two axises. In detail, for applications that need a limited I/O the on board resources of IAS 02 itself are enough. On the board are installed all the hardware resources needed to completely deal with the axis control problematic, allowing a remarkable saving on the application costs.

Devlopment and set up of program for this board can begin with only the IAS 02 itself. To work it is enough the correct sofware package and the connection to any PC compatible computer through the on board RS 232 serial port. This makes a powerful and low cost developlent system. Modularity and completeness of IAS 02 make it the ideal component to build distributed logic architectures.

Should the User application require more functions that the ones provided by IAS 02 board, it is possible to refer to the wide range of peripherals available in the ABACO® industrial listing.

• Eurocard format size 100x160 mm
• Interface to ABACO® Industrial Bus
• CPU Intel 80C31, 80C32, 87C51, 8052 AH BASIC, 320 DALLAS, etc
• 72K of on board memory divided as follows 32K EPROM, 32K RAM and 8K RAM backed through Lithium battery, that can backup also a Real Time Clock capable to manage day, month, year, day of week, seconds, minutes, hours
• 2 RS 232 one of which in full-duplex and one in half-duplex in output (if using software MCS 52 BASIC)
• One 8 pins Dip Switch software readable
• 9 TTL I/O signals directly managed through the on board CPU
• 2 lines of D/A Converter with resolution 12 Bits max 7 µs of Settling Time
• The two D/A Converter are galvanically isolated form the on board logic
• The two output voltages are in the ranges: 0/+5; 0/+10; +5/-5; +10/-10; +2.5/-2.5 Vdc.
• On board DC/DC Converter for galvanically isolated supply of the D/A Converter section
• Three 16 bit Counter/Timer software settable
• Galvanically isolated interface for 3 Bidirectional Encoders
• Open Collector NPN inputs
• Visualization through LEDs of each Encoder input line status
• Input section for Encoder acquisition or Count software manageable capable to acquire the following combinations:
  • Three 16 bit Bidirectional Encoders
  • One 32 bit bidirectional Encoder and one 16 bit bidirectional Encoder
  • One 48 bit bidirectional Encoder
• Separated use and management of Three zero signals
• Indipendent setting of the multiplication factor for the impulses coming from the bidirectional encoder. The factors available are 1; 2; 4
• Watch Dog settable as Monostable or Astable
• All the interface signals to the external world (D/A converter and encoder acquisition) are optocoupled. This warrants a galvanic isolation between on board electronic and external electronic preventing the problems due to electromagnetic noise.
• Unique power supply +5 Vdc, 800 mA
• Wide range of software development packages like:: Monitor; Debugger; Assembler; GET 51 and BASIC Interpreter; BASIC Compiler, BXC51 and C Compilers; DDS, CMX, FORTH; PLM 51; etc.
